Description
The Onesto 10A 3P 3 kA Mini Circuit Breaker is a compact, yet robust protective device designed for three‑phase or multi‑pole electrical circuits. Its triple‑pole configuration ensures that all three phases (or live conductors) are disconnected together — providing full circuit isolation and enhanced safety, especially in installations with three‑phase loads or multi‑wire single‑phase systems.
With a 10 A rated current and 3 kA breaking capacity, this breaker offers reliable protection against overloads and short‑circuit faults, helping prevent damage to wiring, devices, and equipment. The thermo‑magnetic tripping mechanism provides quick interruption when needed, while the C‑curve characteristic ensures a balanced response — sensitive enough for overloads, yet tolerant of normal inrush currents that occur when motors or appliances start.
-
Type: Miniature Circuit Breaker (MCB), Triple‑Pole (3P)
-
Rated Current (In): 10 Amps — ideal for light three‑phase (or 3‑wire) circuits requiring 10 A protection.
-
Number of Poles / Configuration: 3‑pole (3P) — disconnects three live conductors, suitable for 3‑phase circuits or multi‑wire single‑phase setups.
-
Breaking Capacity (Icu / Ics): 3 kA — safely interrupts short‑circuit or overload fault currents up to 3000 A.
-
Rated Operational Voltage (Ue): 240/415 VAC (50/60 Hz) — compatible with standard domestic and light‑commercial/industrial supply systems.
-
Trip Mechanism: Thermo‑magnetic (overload and short‑circuit protection) — cuts power when current exceeds safe limits.
-
Tripping Curve / Characteristic: C‑curve (common for general‑purpose breakers) — provides a balanced response for typical loads.
-
Mounting / Form Factor: DIN‑rail mount (standard 35 mm rail) — easy installation in distribution boards / breaker panels.
-
Protection Provided: Overload protection and short‑circuit protection — safeguards wiring and connected devices from electrical faults or surges.
-
Typical Applications: 3‑phase circuits or multi‑phase installations for light loads, small machinery, motor control circuits, or sub‑circuits requiring 10 A protection. Good for light‑industrial, commercial, or multi‑phase domestic uses.
